Well, if you really consider it a goner then baking it is a last ditch effort. Some have reported success but I think nobody knows if it's a permanent fix or just "for a while".Did that first no joy
Maybe that's what the guy did that sold it to me.Well, if you really consider it a goner then baking it is a last ditch effort. Some have reported success but I think nobody knows if it's a permanent fix or just "for a while".
And it seemingly only works maybe 20% of the time. But an interesting experiment and gives you an interesting story if it works.
The old "bad" pokey looked someone generic compared to the one I cleaned. It had ami stamped on it
I've seen people piggyback new chips over suspect ones to test before desoldering and changing. Would this work with this 4584 or not in this particular application?What Kazoo said. Pokeys will have the number C0122948 on them. (And also a dashed number like -01 after that, but that value doesn't matter.)
Also, when trackballs don't register one direction, the most common (but not the only) cause is the input buffer chip. In your case it will be the 4584 at E/F11. Socketing and replacing that is one of the first things to try. You can also use 40106's as a substitute.
I have Pokeys available, if needed:
FS Parts: - NOS Pokey Pokeys, with warranty - $65 each + $5 sh
I have several NOS Pokey chips available. These are pulls from NIB Atari carts, which I desoldered, cleaned, and tested myself. $65 each, plus $5 shipping (any quantity). (e.g., two for $135 shipped, three for $200 shipped) I'll also warranty these for 1 year. If it dies, just pay to...forums.arcade-museum.com
I have a bunch of Pokeys in my stash. If you need one, DM me.So I have like 3-4 full cases of organized chips from that mega find a while back , pretty sure there could be some Pokey in there but ,what to look for exactly. They are all sorted but not all are labeled. I get there are *I think* 2 Pokeys on the centipede board or is there only just one? I know they are the long socked chips and not the smaller socketed rom chips . Can so.eone post a pic of exactly what to look for and remember we were all new at things once ,so have some mercy.
